Shogun toolbox error freeing memory when SGVector goes out of scope

I built Shogun toolbox ML master on Windows 10 x64, VisualStudio 2019. I run the classifier_minimal_svm sample; it works, but I get this error every time an SGVector goes out of scope

{
 SGVector<float64_t> y_values(100); 
}

there is this error:

Critical error detected c0000374
classifier_minimal_svm.exe has triggered a breakpoint.

Exception thrown at 0x00007FFC395DB0B9 (ntdll.dll) in classifier_minimal_svm.exe: 0xC0000374: A heap has been corrupted 
(parameters: 0x00007FFC396427F0).

I edited a sample and have the error with just these lines of code:

#include <shogun/lib/SGVector.h>

int main(int argc, char** argv)
{
    shogun::SGVector<float64_t> y_values1(100);
    return 0;
}
